Part Descriptions

LP14540-6   Lymphocytes
White blood cells formed in lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin whereas the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T cells (transit through the thymus), B cells or natural killer cells (NK). Source: National Library of Medicine, MeSH 2006

LP14540-6   Lymphocytes
A lymphocyte is a type of white blood cell in the vertebrate immune system.

A lymphocyte count is usually part of a peripheral complete blood cell count and is expressed as percentage of lymphocytes to total white blood cells counted. A general increase in the number of lymphocytes is known as lymphocytosis whereas a decrease is lymphocytopenia.

An increase in lymphocyte concentration is usually a sign of a viral infection (in some rare case, leukemias are found through an abnormally raised lymphocyte count in an otherwise normal person).

A low normal to low absolute lymphocyte concentration is associated with increased rates of infection after surgery or trauma.
